Title: Improvements relating to apparatus for determining angles
IPC: B23D15/00
Filed: 1943-08-19
Abstract: 568,936. Division plates for determining angles. WILLIAMS, J. H., STENNING, A. E., and STENNING, R. H. Aug. 19, 1943, Nos. 13550/43 and 11541/44. [Class 97 (iii)] [Also in Groups XXII and XXIII] The angular positions of a work-piece rotatably mounted in a machine tool are determined by a division plate having optically-worked facets on its edge towards which a collimating telescope is directed. The division plate may comprise two or more superposed plates which, after the facets have been formed, may be displaced relatively to stagger the facets and thus divide the angular intervals when viewed in the telescope. In forming the division plate, the successive facets are formed in definite angular relationship, whilst the plate is held in a succession of angular positions determined in accordance with observations made with a collimating telescope of images formed by reflection in the first and subsequent facets. As shown in Fig. 1, the faceted division plate 10 is mounted on the workpiece (or on a mandrel 14 carrying the workpiece) and is rotated into the required angular positions, the exact settings being attained when an index mark 22 in the focal plane of an autocollimating telescope 16 coincides with the reflection of the mark in the aligned facet. In manufacturing the plate, two superposed glass discs are clamped to a turntable 32, Fig. 4, and the facets are formed on their edges by means of a rotating and oscillating polishing tool 36. By the use of four telescopes 38, 40, 42, 44 adjusted in position by trial and error, four facets at 90 degrees apart may first be formed. The angles may now be trisected and intermediate facets formed by the aid of a fifth telescope 48 and two mirrors 50 clamped to the turntable. Further facets may then be similarly formed by the aid of a sixth telescope 52 in conjunction with mirrors. The final subdivision of the angles and formation of the facets may be effected by the use of graduated graticules in the focal planes of the telescopes. By unclamping the two superposed faceted discs formed as described above and by giving them a small relative rotation to stagger the facets, a compound division plate with finer angular subdivisions is formed. The polishing wheel 36 (which forms the facets without the necessity of first grinding the glass) is mounted on an arm, 56, Fig. 6, pivoted about a spindle 58. A motor 62 operating through belts and through a crank pin 74 imparts a rotary and oscillatory movement to the polishing wheel. A manuallyoperated screw mechanism is provided to feed the polishing wheel towards the facet. In a method suited more particularly for producing a plate with an odd number of facets, two telescopes only are used.

Abstract: 864,937. Automatic exchange systems. GENERAL TELEPHONE LABORATORIES Inc. April 30, 1958 [May 1, 1957], No. 13771/58 Class 40 (4). Connections to a wanted subscriber are effected by automatic simulation of the appropriate dialling under the control of recorded signals. In a fire-alarm system, Fig. 1, closure of a thermal switch 5 starts up a gramophone 2. The signals are amplified and fed to a solenoid 36. A continuous tone at the beginning of the record connects winding 37 to the telephone line so simulating lifting of the handset. The next portion of the record simulates dialling after which occurs a latching zone of continuous tone which drives motor 39 sufficiently long to energize latch relay 31. Latch relay 31 connects pick-up 22 to winding 28 of transformer 29 so that a recorded message can be sent to line. The terminal groove of the record causes the system to return to normal, in known manner. If the originating condition persists the cycle starts again. Access to frequently-wanted subscribers is provided by the apparatus shown in Fig. 3. The subscriber lifts his handset and closes the appropriate switch 67. A magnetic drum 66 is then driven and signals are picked up from the selected track to simulate dialling.
